What is the weather like today?
Is it like this EVERY day? Why?
What is the difference between WEATHER and CLIMATE?
In other words…what it’s like OUTSIDE, right HERE, right NOW
In other words…the AVERAGE of all the WEATHERS
Rotation– one SPIN of the Earth on it’s axis. This takes about 24 hours…one DAY.

This creates a predictable cycle of warmer and cooler periods, or seasons.
Here is the rule to remember… Tilted “toward” the Sun means Summer, tilted “away” from the Sun means winter
room to move, so they spread
apart, meaning LESS molecules
in a given space (LOW pressure)
move as much, so they pack closer
together, meaning MORE
molecules in a given space (HIGH pressure)
middle latitude winds to flow “backwards”, rising at 60 deg. and sinking at 30 deg., even though that is warmer air.
DRAW THIS !!!
Low Latitude (“Tropical”) climates – always hot
Mid Latitude (“Temperate”) climates – hot/cold seasons
High Latitude (“Polar”) climates – seasons either mild or extreme cold
WRITE THESE DOWN !
Polar (High Latitude) zone – either mild temps. or extreme cold
Temperate (Mid-Latitude) zone – seasonal, most varied climates
Tropical (Low Latitude) zone – year-round direct sunlight, always hot
RULE: The HIGHER the latitude, the COLDER the temps.
RULE – The HIGHER the elevation, the COLDER the temperatures.
30 degree change in Houston
45 degree change in Denver
brings in warm, moist air
from the ocean which then hits the mountain and rains
